Few months ago I wrote some search array functions. Since than I found them very useful, so I decided to publish them here. I have added one more function shuffle, which gives new array from given one but with randomly located elements.
function search finds element in array and displays result
function searchB finds element in array and returns Boolean value
function searchCount returns number of apperances of element in array
function union returns union array of two arrays
function shuffle simply shuffles elements of given array and returns new array
will continue to add more.
